AR8200 Mk3 hand portable radio receiver ADDENDUM (paperwork V1.0)

Due to continuous development of our products, the AR8200 has evolved into the Mk2 and Mk3 versions. As a result, operation

differs from the original AR8200 in a few areas, please note the following changes to the AR8200 operating manual:

1 The front ten-key keypad has been rearranged in line with customer requests placing the 0 zero key underneath the

8 eight key, as is standard practice with push button telephones. On page 9 section 1-5-1 of the English language operatingmanual, the graphic should now look like (the revised keypad has been used on the Mk3 and Mk2 versions):

2 The Mk3 and Mk2 versions feature a built-in TCXO (Temperature Controlled Crystal Oscillator) in place of the referencecrystal. This ensures the best levels of frequency stability and minimum spurii.

3 In place of the previous rubber covered aerial, a telescopic whip on a swivel base is supplied (Mk3 and Mk2 versions).The whip provides the very best performance, especially on the VHF bands with the ability to adjust the length of the telescopicwhip aerial to peak received signal strength (the higher the frequency, the shorter the aerial). An alternative flexible smallerwhip aerial is available as an option where durability and smaller size is important. Please refer to page 7 section 1-4 of theEnglish language operating manual, line two of the table should now read telescopic whip aerial.

4 The relationship between level squelch and signal meter has been revised. This affects VFO SEARCH LEVEL SQUELCH(page 47 section 4-4-3 of the English language operating manual), SCAN LEVEL SQUELCH (page 68 section 7-8-2 of theEnglish language operating manual) and PROGRAM SEARCH LEVEL SQUELCH (page 84 section 8-7-2 of the Englishlanguage operating manual).

In each case, the following table replaces that previously employed:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

Mk2 8 13 18 24 29 35 39 44 50 55 58 62 71 77

Mk3 7 15 18 24 28 31 42 50 59 64 72 80 85 89

As a result, the typical level at which the legend will be extinguished has changed.

5 The batteries supplied with the AR8200 have been changed. To ensure that a completely full charge is established, pleaseassume the full charge time as follows, this replaces the reference given on page 19 section 1-6-4 of the English languageoperating manual.

While in a text input menu, for flashing FUNC legend then refer to the following table.

Look for the required character in the table then PUSH the key shown to the horizontal-left followed bythe key shown above the required character (do not push both keys together). The first keypush will produce a character on the screen which will be replaced with the required character when thesecond key is pushed, the cursor with then move one place to the right.

&Note: The CASE SHIFT key is used to access lower case letters.

Section 13-3

Example:To select the letter N until the flashing FUNC is displayed.

, the number 4 will be displayed, , the desired N character will be

displayed and the cursor will move one position to the right. The flashingFUNC legend will continue to

flash, if it is not required further for it to be removed from the LCD.

Example:To select the letter e until the flashing FUNC is displayed.

, the number 5 will be displayed, to instruct the CPU that a lower

case letter is required (CASE SHIFT) , the desired e character will be displayed and the

cursor will move one position to the right. The flashingFUNC legend will continue to flash, if it is not

required further for it to be removed from the LCD.

14-1 CONFIG BEEP

The AR8200 emits confirmation beeps while the keypad and sidekeys are used. A HIGH pitched beep indicates correct operationwhile a LOW pitched beep indicates that an error or unexpectedentry has taken place. The volume of the beep is independent of

the main volume control and can be separately defined. It isrecommended that the beep facility be enabled, especially in theearly days while gaining familiarity of the receiver.

Beep is setup in the CONFIG menu. To access the config

menu . The first item in the

config menu is BEEP, the default is beep on with a volume level of 09. Use the main dial or keys to vary beep level between the range of OFF and 01 to 09 with 09 being the loudest. The

key may be used as a short cut to 05.

to accept the data and return to a standard display. Alternatively

to abort entry or to move to the next item on the config menu (LAMP).

14-2 CONFIG LAMP

The AR8200 is equipped with high intensity green LEDs to illuminate the LCD and front panel keypadwhen operating in areas of low level lighting.

While the AR8200 is switched on and connected to an external power source such as the chargeror d.c. lead, the lamp will be PERMANENTLY ON and cannot be switched off. The lamp will go outwhen the AR8200 is switched off (when the batteries are being charged etc).

The lamp may be configured in three ways:

AUTOThis setting is relevant when operating from internal batteries only. The lamp will automatically illuminatewhen the front panel and side panel keys are used. The lamp will remain illuminated for a further fivesecond after the last key push and will then switch off. This is a good compromise setting for bestvisibility and battery life.

CONTThis setting is relevant when operating from internal batteries only. The lamp will CONTinuouslyilluminate the front panel and side panel keys. The lamp will only extinguish when the AR8200 isswitched off. Of course continuous operation of the lamp will drain the internal batteries more quickly.

OFFThis setting is relevant when operating from internal batteries only. The lamp remains permanentlyextinguished, this is useful to maintain maximum battery life when used in areas of high light levels.

The LAMP is setup in the CONFIG menu. To access the config menu

. to move the cursor to the LAMP selection point. Use the main dial or

keys to toggle the lamp between AUTO (default), CONT and OFF. The key may be used

as a short cut to AUTO.


to abort entry or to move to the next item on the config menu (CONTRAST).

14-3 CONFIG CONTRAST

The AR8200 is equipped with variable LCD contrast which is adjustable in 32 steps to provide bestvisibility under different viewing angles, extremes of ambient light & temperature (and between sets dueto variation).

The default setting for contrast is 14. The display generally becomes too dark to read around 20 and too

feint around 02, the key may be used as a short cut to 14.

The CONTRAST is setup in the CONFIG menu. To access the config menu

. twice to move the cursor to the CONTRAST selection point. Use the

main dial or keys to vary the contrast level to achieve best visibility.

to abort entry or to move to the next item on the config menu (AUTO PWR-OFF).

14-5 CONFIG Auto power off

An auto power off facility is available to switch the AR8200 off automatically after a programmable periodof squelch inactivity, this prevents the batteries from becoming flat when monitoring a completely inactivefrequency.

&Note: Be careful how you use auto power off as it might catch you out one day (if a short

auto-power-off period has been set), auto power off setting is not cancelled with power off / on

if the AR8200 appears to switch itself off for no reason, check to make sure that you haventenabled auto power off (there is no associated LCD legend).

AUTO POWER OFF is setup in the CONFIG menu. To access the

config menu . five

times to move the cursor to the AUTO PWR-OFF selection point.Use the main dial or keys to vary the time between 0.5 hours

to 9.5 hours in 0.5 hr increments, the key may be used

as a short cut to OFF.

When the AR8200 squelch closes, the CPU will wait the length oftime programmed in auto-power-off before automatically switchingthe AR8200 off. If the squelch opens again before auto switch off time has elapsed, the radio will notpower down and the counter will be reset (i.e. an open squelch defeats auto power off).


to abort entry or to move to the next item on the config menu (REMOTE BPS).

14-6 CONFIG REMOTE BPS

The REMOTE BPS menu is used to configure the RS232 computer control settings as it is important thatthey exactly match those of an associated computer connection or another AR8200 (connected via theoption socket and optional leads).

The REMOTE BPS parameters are setup in the CONFIG menu.

To access the config menu .

six times to move the cursor to the REMOTE BPS

selection point. Use the main dial or keys to vary the RS232

baud rate between 4800bps, 9600bps and 19200bps. Thekey may be used as a short cut to the default of

9600bps.

is adjustable between 00 and 99, the default is 00. The key may be used as a short cut 00.

&Important note: It is extremely important to set the RMT-ID to 00 for normal operationof the RS232 connection and clone of data between radios.


to abort entry or to move to the next item on the config menu (FREQ DISP).

14-7 CONFIG FREQ DISP

It is possible to instruct the AR8200 NOT to display frequencies while in memory read, search and scanmodes (should you wish for prying eyes not to see specifically what you are listening to). Liberal use oftext comments is recommended if you disable frequency display (turned it off) unless you choose tohave really anonymous operation!

&Note: Frequency display will be provided in VFO and VFO search and VFO scan even withthe frequency display disabled.

The FREQUENCY DISPLAY parameters are setup in the CONFIG

menu. To access the config menu .

eight times to move the cursor to the FREQ DISP

selection point. Use the main dial or keys to toggle between

ON and OFF. The key may be used as a short cut to ON

(which is default).

(15) Band scope

The AR8200 is equipped with a flexible band scope function which is capable of graphically displayingband activity. The maximum frequency span width is 10 MHz, you may zoom in on activity to a spanwidth of 100 kHz. Centre frequency is displayed and a marker may be manipulated to ascertain thefrequency of activity using the graphical display. One trace may be saved to memory for recall at a later

time and may be overwritten at will. The trace may also be saved and loaded from the optional EM8200external memory slot card.

&Note:Priority operation is disabled when the band scope is in operation. Audio is muted.

The optional RU8200 is inoperative when the band scope is in operation.

It is suggested that the band scope facility is experimented with on a constantly active band such asVHF Band-II broadcast.

15-1 Starting the band scope

To start the band scope . The frequency span width will be set to 10 MHz with the last

frequency displayed in 2VFO, search, scan or memory read mode being used as the centre frequency.AUDIO IS MUTED.

The centre frequency is displayed in the top left of the LCD, one pixel will be missing from the centre ofthe graphical base line indicating centre frequency position.

A progress cursor which comprises of a single pixel on the graphical base line travels from left to rightupdating the band scope display this confirms that the band scope is IN OPERATION (especiallyuseful when a trace is simply being updated or no signals have been located).

The frequency span width is displayed in the upper right corner of the LCD, at default this is 10 MHz.

The frequency marker legend MKR is displayed on the second line of the LCD, the marker is alsorepresented graphically by an upturned triangle (initially placed above-centre of the graphical trace).When first activated, the centre and marker frequencies are the same (but may be altered).

The graphical trace is built-up from left to right. If no transmissions are encountered the display willsimply form a horizontal line around two pixels in height. When activity is located, vertical lines areproduced on the LCD, the stronger the signal the higher the line.

&Important: To monitor the transmission of the marker frequency and hold the

key. The progress of the scope is halted when the key is held. Squelch setting

has no effect on the band scope trace.

15-2 Exit from band scope

To exit the band scope or or .

15-3 Setting frequency span width (waveform enlargement)

The frequency span width may be adjusted between the limits of 10 MHz (default) to 100 kHz using

the keys. The span widths available are:

10 MHz 35s for full trace approx.




500 kHz 3s for full trace approx.

200 kHz 6s for full trace approx.

100 kHz. 3s for full trace approx.

When the frequency span width is altered, the trace restarts. to refresh the trace from

the start.

15-4 Moving the marker

To move the marker position use the keys, the channel step will be dependant upon the span

width resolution. To monitor the marker frequency and hold the key. The progress of

the scope is halted when the key is held.

15-5 Marker to strongest signal (peak search)

To simplify operation, it is possible to jump the marker to the strongest signal of the current graphical

trace (peak search). and hold the key until the legend is displayed indicating

that the marker is set to the strongest graphical signal. and hold the key to monitor

the selected frequency. The keys may be used to hop between the strongest few transmissions.

to disable peak search, the will be removed from the LCD.

&Note: If no signal is found above the background level (or if there hasnt been time allowed

for a trace to form), peak search will not operate and an error beep will be emitted (if beep isenabled). This facility cannot be used with a span width of 100 kHz.

Resolution is 10 kHz with a 12 kHz IFfilter selected (NFM or AM) so that onepixel represents 140 kHz at maximumsignal strength

Resolution is 2 kHz with a3 kHz filter (USB, LSB, CW)

15-6 Entering a new centre frequency

To enter a new centre frequency, simply tap the wanted frequency into the keypad. The legendCENTRE FREQ will be displayed on the top line of the LCD with entry taking place on the second line.

To complete entry in MHz format . The marker will be automatically set to the centre

frequency but the frequency span width will be unchanged.

15-7 Transfer of marker frequency to VFO

There are two ways in which the marker frequency may be transferred to VFO for long term monitoring.

Transfer to 2VFO retaining VFO data

to move marker frequency to 2VFO, receive mode and step

are those of the VFO.

Transfer to single VFO with 10 kHz tuning step

Hold the key then to transfer marker frequency to single VFO,

receive will be that used in VFO mode but the tuning step will always be 10 kHz to allowsensible re-tuning in VFO mode for best reception of the transferred marker frequency

15-8 Peak hold

The PEAK HOLD facility is used to build up an image of bandactivity over a period of time, the display is not totally cleared eachtime a trace is made, only strong signals are added.

To toggle PEAK HOLD on/off ,

the HLD legend confirms when peak hold is active.

The keys may be used to move the marker position and

key may be held to monitor activity on the marker

frequency.

15-9 Saving active trace to memory

To save the current trace to internal memory (for later retrieval)

. It is suggested that the peak hold facility

be employed before saving a trace so that it provides moremeaningful information.

If the optional EM8200 is used, it possible to save four furthertraces to external memory. Refer to section 18-6-7of this manual

for further information regarding this feature.

15-10 Loading stored band scope traces from memory

Providing a trace has been previously stored to memory, it is possible to recall it to display using the key

sequence . The legend RCV (in the place of MKR) indicates that a

stored trace is currently being displayed.

The AR8200 will no longer sweep the frequency range but the key may still be used to monitor

the marker frequency. Key in a new centre frequency to return to a real time band scope.

It is possible to move the marker across the graphical trace using the keys. Waveform enlargementis available by changing the frequency sweep width using the keys.

If the optional EM8200 is used, it possible to load any one of fourfurther traces from external memory. Refer to section 18-6-7ofthis manual for further information regarding this feature.

(16) Sleep

It is possible to instruct the AR8200 to automatically switch-off after a predetermined time, this isparticularly useful if you know that you may be called away from the receiver or listen to it while inbed and dont want the batteries to become completely flat.

Use the key sequence to accesses the SLEEP menu.

Use the main dial, keys or key to toggle sleep

on/off. For convenience SLEEP is default ON when this menu isaccessed so that you have simply to access and exit the menu forsleep to be activated.

Either to save the changes and exit the menu

or to move the cursor to the sleep TIME menu. Use

the main dial to set sleep time in 1s increments or keys toincrement in 10 seconds, the range is between 1 and 120 minutes,

is a short cut to 60 minutes (default).

The AR8200 will automatically switch off after the programmed time has elapsed.

To accept the data and activate sleep . The display will return to standard format and

the circular CLOCK legend will be displayed to remind you that automatic power off will take place.

The next time that the AR8200 is powered on, the sleep facility will be automatically cancelled.

Connect the optional CC8200 computer control lead to the optionsocket and connect to a computer. The command protocol isprovided with the CC8200 on floppy disk as an Adobe AcrobatPDF file.

The RS232 parameters may be defined using the CONFIG menu.Baud rates (transfer speed) may be set to 4800, 9600 or19200bps. It is also possible to set an address to facilitateconnection of up to 99 AR8200 to a single port for customoperation, the addresses may be set between the limits of01 to 99 with 00 representing single radio operation.

When operating from external RS232, the legend will be displayed on the LCD. Please refer to

section 14-6of this manual for information on the CONFIG menu settings.

17-2 CLONE of data via the option socket

It is possible to copy data (clone) between two AR8200 receives using the optional CO8200 clone lead,no computer is required.

&Note: As clone of data takes a while, it is suggested that the receivers are connected to

external power or at least that the NiCads are FULLY charged while cloning data. Do notprematurely terminate the clone of data in any way or data corruption may occur do notswitch either AR8200 off, disconnect the CO8200 or disconnect power. Data can be copied ineither direction but the EM8200 is not supported, only INTERNAL data can be copied betweenradios.

Connect each radio to the CO8200 lead and switch them on. The following table indicates the facilitiesavailable:

ALL DATA All data is transferred from one radio to the other(approx. 8 minutes 30 seconds)

SEARCH BANK A specific search bank is copied to the same or different banknumber of the second radio (approx. 3 seconds)

ALL SEARCH All search banks are copied from one radio to the other keeping

bank numbers the same (approx. 1 minute 30 seconds)MEM BANK A specific memory bank is copied to the same or different bank

number of the second radio. Ensure that the memory banks havethe same sizes allocated (dynamic memory bank resizing) or datamay be lost (approx. 30 seconds)

17-2-1 How to clone data

Ensure that the RS232 baud rate is set to the same speed for bothradios and that the address is set to 00 on both units (refer tosection 14-6of this manual for information on the CONFIG menusettings).

a) Pick the radio which you wish to copy TO (target)

First decide which unit will be used to receive (LOAD) the data.

to access the COPY RS232C menu. The key acts as a

toggle between LOAD and SAVE (the default is LOAD), alternatively use the main dial or keysto select LOAD.

b) Decide WHAT you want to copy

the key to move down the COPY RS232C menu, the cursor

will be flashing to the left of the item ALL-DATA. If you want to load

ALL DATA , alternatively use the main dial or

keys to select the type of data you wish to load (copy) from the other

radio. .

The bottom two rows of the LCD will display the legends LOADING !!and a number. The number will start counting downward when the copy

process starts (when the other radio has been instructed to SAVE), themore data you have selected, the higher the number for ALL-DATA thenumber will typically be 448.

c) Configure the radio used to SAVE

On the second radio, to access the COPY RS232C menu.

The key acts as a toggle between LOAD and SAVE (the default is LOAD), alternatively use

the main dial or keys to select SAVE.

the key to move down the COPY RS232C menu, the

cursor will be flashing to the left of the item ALL-DATA. If you

want to load ALL DATA , alternatively use

the main dial or keys to select the type ofdata you wish to save (send) to the other radio. Itis most important that the type of data selected

is IDENTICAL on both radios.

.

The bottom two rows of the LCD will display the legends SAVING !! and a number which will start

(18) Slot card socket

The slot card is located in the bottom of the AR8200 cabinet and protected from dust etc by a door whichis hinged toward the back edge of the cabinet. To access the socket place the AR8200 on its back and

open the front edge of the protective door. Be careful to keep dust and dirt from this socket and toprevent liquid entering the AR8200 via this socket. Ensure that no conductive material is allowed to shortcircuit the socket which may damage the receiver.

18-1 Optional slot cards

Any one optional card may be fitted at any time. Do not use anything other than the genuineAOR slot cards.

The slot card has five main uses:

1. VI8200 Voice inverter (analogue) in 157 steps

2. CT8200 CTCSS squelch & search

3. TE8200 Tone eliminator in 256 steps

4. RU8200 Chip based recording and playback, 20 seconds approx.

5. EM8200 External extended memory, backup 4,000 memories, 160 search

banks (can hold as much data as 4 x AR8200)

Signal types depend upon the slot card fitted, these include:

l 4.2V PSU

l GROUNDl CARD RECOGNITIONl AUDIO IN

l AUDIO OUTl CARD CONTROL INl CARD CONTROL OUT

18-1-1 Fitting the slot card

Always switch the AR8200 off when inserting slot card. To access

the socket place the AR8200 on its back and open the front edge ofthe protective door. With the AR8200 keypad facing upward, hold theslot card so that its label also faces upward. An arrow printed on the slotcard indicates the direction of entry into the AR8200, insert the connec-tor end of the slot card into the AR8200 (the end you will be left holdinghas groves to help grip). Without using excessive force, use a thumb to push the slot card fully intothe body of the AR8200 until it is slightly recessed into the bottom of the receiver. Close the hingedslot card compartment cover.

&Note: The AR8200 will automatically recognise each optional slot card, there is no need to

initialise the option (except for the EM8200, see later).

When slot cards are fitted, the AR8200 menu system dynamically changes to reflect the slot card

Section 18, 18-1, 18-1-1

currently fitted. If however the AR8200 thinks that a slot card option is fitted when it isnt, accessthe slot card menu and disable the option.You may wish to leave certain items selected if they are not affecting current operation in order tominimise reprogramming when slot cards are inter-changed at a later time.

18-1-2 Removing the slot cardAlways switch the AR8200 off when removing a slot card. To access thesocket place the AR8200 on its back and open the front edge of the protectivedoor. An EJECT slider is mounted on the left hand side of the AR8200 cabinet.With the AR8200 keypad facing upward slide the EJECT control toward the sidekeys of the AR8200, the thumb is best for this purpose hold the thumb of theother hand one or two centimetres (one inch) from the bottom of the slot card toprevent it shooting out of the AR8200 and falling on the floor.

The stiffness of the cards varies and may be tighter when used for the first fewtimes, the EJECT slider needs quite a push but dont use excessive force or

tools!

18-2 VI8200 optional voice inverter slot card

The VI8200 enables the AR8200 to recover intelligible audio from certain types ofanalogue transmission which would otherwise sound scrambled. They operate bysplitting up the audio spectrum and flipping the upper and lower tones around acertain frequency point. The VI8200 enables 157 different flip points to beselected in the frequency range of 2.4 kHz to 5.6 kHz.

Insert the VI8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have

recognised that the VI8200 has been fitted so will present the voice inverter menu.

The legend VOICE INVERT confirms selection of the voice inverter menu. the

key to toggle the voice inverter on/off (default on). Use the main dial or keys to make selection of tone in 157 steps from 0 to 156, the keys are used to incrementselection by 10.

To accept the data input (when audio is intelligible) , alternatively to abort entry

.

Refer to the relationship table between value and flip frequency:

Frequency (kHz) 2.4 2.8 3.2 3.6 4.0 4.4 4.8 5.2 5.6 6.0 6.15

Inverter value 0 37 64 86 102 116 128 138 146 154 156

When the voice inverter has been activated and you exit from the voice inverter menu back to VFO, the

legend v 68 will be displayed in the bottom right corner of the LCD. The legend v indicates that the

inverter is active while the legend 68 indicates the currentflip value in use.

To speed up the toggling of voice inverter, to

effectively toggle the voice inverter option on/off. This isachieved as the default is set to voice inverter ON (by accessing

the voice inverter menu) so that every time the voice invertermenu is accessed, the voice inverter is automatically activated.

1. For example, assume that the voice inverter is

currently OFF. to access the voice inverter menu, the voice inverter

menu cursor will moveto ON.

2. to revert to VFO mode with the voice inverter on.

3. to immediately toggle the voice inverter off.

The sequence then repeats each time you .

&Note: Using the voice inverter to monitor normal transmissions willcause them to distort and sounds rather like tuning across a busy shortwave band using USB.

18-3 CT8200 optional CTCSS slot card

The CT8200 enables the AR8200 to search for 50 CTCSS tones which may be inuse on the current receive frequency and to save a specific CTCSS tone (fromthe 50 tones available) into each VFO, each search bank and every memorychannel individually. CTCSS is used by many amateur band repeaters, publicutilities and private mobile radio services where shared resources are used,CTCSS ensures that operators only hear traffic intended for them.

Insert the CT8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have recognised that the

CT8200 has been fitted so will present the CTCSS menu.

The legend CTCSS confirms selection of the CTCSS menu. the key or use the

keys to toggle the CTCSS facility between OFF /ON /SRCH (default is off). To abort entry and

exit the menu .

&Note: You wont be able to audibly hear a CTCSS tone due to the low frequencies

employed and audio characteristics of the AR8200 (and other receivers).

While in the CTCSS menu, to activate the CTCSS facility (the LCD legend ON

is displayed in reverse highlight).

Use the main dial or keys to make selection of CTCSS tone from the 50 available, the valuecannot be adjusted when the menu is set to OFF. The current CTCSS tone is displayed on the

last-but-one line of the LCD, the legend is displayed to the left of the CTCSS frequency when

the current receive frequency is using the displayed CTCSS tone, this assists manual selection ofthe correct tone.

To accept the data input , alternatively to

abort entry . The selected CTCSS tone may

be used in VFO (separate CTCSS tones may be held in eachVFO) and independent CTCSS tones saved in each searchbank and memory channel.

While in VFO, the legend CTC is displayed in the lower leftcorner of the LCD to indicate that CTCSS is active. The audio willbe completely muted until a transmission occurs which containsthe specified CTCSS tone even when the squelch is set fullyanti-clockwise (open), it is normal for the occasional splutter to be produced as CTCSS typefingerprints naturally occur in everyday transmissions and background noise.

Scan & search banks: It is even possible to scan & search with the squelch open when CTCSS isactive but scan/search rates will be reduced significantly. To achieve the best speeds, set thesquelch until the S legend is extinguished in the usual manner.

Refer to the CTCSS table of available tones:

94.8 100.0 103.5 107.2 110.9

114.8 118.8 123.0 127.3 131.8

use the CTCSS SEARCH facility to discover whatfrequency is employed.

Place the AR8200 into VFO mode then

to access the CTCSS menu.

to highlight the SRCH legend

then to accept the input and exit

the menu.The LCD legend CT-S will be displayed in thebottom left corner of the LCD to indicate that CTCSS SEARCH is in operation. While in 2VFOmode, the standby frequency will be replaced with the legendCTCSS 205.5 Hz when a CTCSS tone of 205.5 Hz has been located, otherwise the appropriateCTCSS frequency will be displayed.

Each memory channel, VFO and search bank can hold different CTCSS frequencies and different

settings of CTCSS squelch and CTCSS search (i.e. you can have CTCSS search active in VFO butCTCSS squelch active in memory channels).

If you are uncertain where CTCSS may occur and wish to experiment with CTCSS search, simplyactivate the CTCSS SEARCH facility while monitoring a broadcast frequency(such as Band-II) which has a rich audio range (playing music etc).

&Note: As CTCSS search has to check all 50 possible frequencies,

it may take up to 15 seconds for the CTCSS tone to be identified.

18-4 TE8200 optional tone eliminator slot cardThe TE8200 enables the AR8200 to ignore certain transmission tones whichwould otherwise stop the scan and search processes. Pilot tones are oftentransmitted by public utility services and railways making their transmissionstroublesome and fatiguing to monitor without the use of the TE8200. There are256 values for the tone eliminator ranging from 0 to 255 representing a frequency range of 0.4 kHzto 4.2 kHz.

Insert the TE8200 slot card and switch the AR8200 on, select VFO mode.

to access the slot card option menu. The AR8200 will have recognised that theTE8200 has been fitted so will present the tone eliminator menu.

To accept the data input , alternatively to abort entry . When

active, the LCD legend T.EL

will be displayed in the bottom left corner of the LCD.

Refer to the table to reconcile value with frequency:

Frequency (kHz) 0.4 0.6 1.0 1.4 1.8 2.2 2.6 3.0 3.4 3.8 4.2

60 110 170 200 220 230 235 240 245 248 250

Tone eliminator setting and value may be held separately in each VFO, search bank and memory

channel.

The squelch should be set to threshold in the usual manner. Operation continues as normal with thetone eliminator active, however if a transmission is encountered whichcontains a pilot tone which matches the current setting of the tone eliminator,the squelch will close allowing the scan and search processes to continuei.e. the AR8200 will NOT think that it has found an active receive frequency orblank carrier.

&Note: The tone eliminator does not remove whistles from the

loudspeaker, it purely allows scan & squelch to continue unhindered.

18-5 RU8200 optional record & playback slot card

The RU8200 enables around 20 seconds of audio to be recorded to a chip within the RU8200 forplayback at a later time. The chip may be recorded to time and time again overwriting the previousrecordings. The recording may be played back over and over, very useful if you have grabbed aninteresting recording! The RU8200 may be used in VFO, scan, search and memory read modes.

Insert the RU8200 slot card and switch the AR8200 on, select VFO mode.

8/14/2019 Section 1 (1) AR8200 Index

27/142

128

&Note: You cannot scan or search the backup information, data

must be loaded back into the AR8200 before these processes can be activated.

&Important note: Never remove the EM8200 with the AR8200 switched on, especially

while data is being saved / loaded to and from the AR8200 or data corruption may occur.Saving all data takes some time, it is recommended that external power be used whilecopying large volumes of data to / from the EM8200 (or at least be sure that the batteriesare well charged). No liability in any form will be accepted in respect of data savedto / loaded from the EM8200 option.

&Note regarding write protect: If the write protect has been globally set to ON

(ALL PROTECT) in the configuration menu ( ), data load will

be unsuccessful and no data will be loaded. Individual memory channel protect, memorybank protect and search bank protect will be ignored during data load from the EM8200.

&Note regarding possible NOISE: A small increase in noise may be noticed while the

EM8200 option is fitted inside the AR8200, this will disappear when the EM8200 is removedfrom the receiver. If signals are very weak or noise is a problem, temporarily remove theEM8200 option.

The following table indicates the data types which may be saved to / loaded from the EM8200:

1 ALL-DATA All memories, search banks, band scope andenvironment data

2 ALL-MEM All memory channels

3 MEM-BANK One specified memory bank

4 ALL-SRCH All search banks

5 SRCH-BANK One specified search bank

6 B-SCOPE Band scope data

18-6-1 Initialising (formatting) the EM8200 before use

The EM8200 has been tested during manufacture but is not fully formatted. Before you use the EM8200

for saving real data, you must format the memory, this only needs to be carried out once in the life of theEM8200 (similar to formatting a computer disk drive).

To format the memory, simply execute a SAVE ALL to each of the four memory locations of the EM8200(0, 1, 2 & 3).

If you do not format the memory, you will still be able to carry out SAVE ALL (item 1 in the table) but thespecific data saves (items 2, 3, 4, 5 & 6 will not operate). If you do not format the memory and laterattempt to use a specific memory save or load, an error beep will sound (if beep is enabled).

To access the COPY EXT-MEM menu (which is used for the EM8200 data save / load and has beenselected dynamically in place of the COPY RS232C menu as the AR8200 recognises that the EM8200 is

fitted) . Four significant lines of menu are displayed:

(19) Trouble shooting

Should the AR8200 appear to act strangely, check out the following suggestions to see if the problemcan be overcome. Failing this, switch off the AR8200, disconnect any external power connection andremove one battery from the radio (if you have batteries fitted). Wait for at least 30 seconds then re-fit

the battery (if in use) or re-connect the external power and switch the radio on again with a of

the key.

Check to see if the problem has cleared.

19-1 Soft reset of microprocessor

If removing power and switching the AR8200 off / on does not help, try a soft reset of the microprocessor.

Soft reset is achieved by powering-up the radio with the key held, do not release the

key until the opening message has performed and a frequency is displayed in 2VFO mode.

All scan & search environments are cleared, bank link is set off and the receiver frequency will be set to88.000 MHz for both VFO-A and VFO-B. The beep will be enabled and set to default as will lamp andLCD contrast. All memory and search bank data will be intact.

19-2 Other trouble shooting suggestions

AR8200 will not power on. Check that the set is connected to external power (12V d.c.) or thatbatteries are fitted and are fully charged.

There is no audio. It may simply be that the squelch is closed or volume is turned down. and

hold the key and adjust the volume to a comfortable level. Ensure that no external loudspeaker,

headphone or earphone is in use. Check that the band scope is not in operation.

19-3 Trouble shooting - Take note of the following

Select scan cannot operate in conjunction with mode scan. Select scan is disabled when priority isengaged.

Priority is disabled when the band scope is in operation. If a long DELAY time is set, priority eatsaway at delay time causing it to shorten. If the optional CT8200 slot card is in use, CTCSS SEARCHcannot operate with priority engaged due to the required CTCSS search time being quite long.

When POWER SAVE is on, response from the AR8200 may be sluggish and there will be periods ofno receive.

If the key is being used to display a frequency with FREQUENCY OFFSET in use, this offset

frequency cannot be stored into memory.

The squelch may not operate promptly (as you may expect) when monitoring in USB, LSB, CW andNAM modes due the narrow bandwidths employed. This is a fundamental characteristic of the squelchcircuit. Audio may remain even though the S squelch legend may have disappeared for a couple ofseconds. It is suggested that LEVEL squelch be used as an alternative in this situation.

There are no internal operator adjustments. In the unlikely event of servicing being required,please contact your dealer for technical assistance.

(21) Aerial (antenna), earths & propagation

The subject of aerial choice and earth can be quite complex. There are many advantages and disadvantages to consider beforeconnecting an external aerial to your receiver. One interesting phenomena is that aerial theory and practice can be surprisinglydifferent. Keeping common sense in mind it is one of the few remaining areas for listeners to easily experiment and often achievefantastic results.

Whip aerialThe supplied semi-flexible whip aerial should give adequate results for general hand-held operation on the VHF and UHF bands.A longer wire aerial or telescopic whip should be considered for listening to the short wave bands. The AR8200 is supplied with aferrite bar aerial for medium wave reception, for best results, rotate the receiver as the bar aerial is directional.

Mounting locationIt is important to mount any external aerial as high as possible and in clear space although this is more important at VHFfrequencies than for short wave. If possible the aerial should have a clear path to the horizon. Results are usually disappointingwhen an installation is in a loft space.

Long wire aerialsFor short wave reception a random length of long wire approximately 10 to 20 metres in length forms a good compromise. The wireshould be connected to the centre pin of a BNC plug then connected to the BNC aerial input on the top of the AR8200. If possibletry to locate the receiver close to a window so that the wire has the shortest and most direct run from the rear of the receiver to theoutside world.

DisconeFor wide coverage in the VHF-UHF bands a compromise has to be met and the most popular aerial is a discone (AOR DA3000).Their appearance is like a large spider or umbrella without the covering material, the better models have about 16 elements.Typical usable coverage starts from about 25 MHz and extends continuously to 500 MHz 1300 MHz or even 2000 MHz. Thecoverage peaks and dips throughout its range as the elements interact to provide the widest possible coverage. Due to theirnecessary construction discone aerials are a little prone to wind noise due to vibration and possible damage in severe gales.

Filters

A VHF civil AIRBAND FILTER is available (ABF125), this will help minimise the possible effects of breakthrough when listening toVHF airband in Band-II VHF high signal areas or when connected to external aerials.

Earth systemsA separate EARTH connection made to the outer (braid) connector of the BNC plug may improve aerial efficiency and reduce noise.Suitable earth points include connection to a water pipe, central heating radiator or external earth rod. If fitting a separate externalearth rod, consider the implications carefully if your mains supply uses Protective Multiple Earth (PME) system. If in doubt consultan experienced electrician. Connecting an external earth wire may greatly reduce the local noise encountered when listening on theshort wave bands. It is very important to provide a good earth should you use an aerial tuning unit.

A short length of thick gauge earth wire may be connected to a nearby central heating radiator or water pipe but never use a gaspipe for earthing. Ideally a separate earth rod should be used but the length between the receiver and rod becomes restrictive,if too long the earth system may well pick up noise rather than remove it.

PropagationVHF and UHF transmissions generally only propagate relatively short distances when compared to short wave signals. For allintents and purposes they may be considered as line-of-sight plus a bit.

Where as point to point communication between mobile users or when in built up areas may only be a couple of kilometres, aircraftat heights of 30,000 feet may be heard for many tens of kilometres (100 to 300 with the right conditions).

Unlike VHF and UHF transmissions which generally propagate only on a localised basis (to the horizon plus a small amount), shortwave transmissions may travel for many thousands of kilometres. Depending upon the frequency in use, time of day, season of theyear and sun spot activity, transmissions may propagate completely around the World.

Luckily the frequency spectrum of short wave is often reflected back down to Earth by the upper layer of the Earths atmospherecalled the ionosphere. When the reflected signals reach the Earth again they may either be received or reflected back up intospace. If lucky, they will be reflected by the ionosphere yet again down toward the Earth providing reception into another andpossibly more distant location. Depending upon the time of day and desired skip distance, different frequencies will be selected by

Radio Amateurs and commercial users such as Oceanic Air Traffic.

(5) Memory channels & banks

It is convenient to store commonly used frequencies into a memory channel along with mode etc, thissaves having to key the data in over and over again. Memory read is very straightforward and quickwhen compared to re-typing all data.

5-1 Memory channel overview

Think of memory channels as pages in a notebook each of which is numbered to identify it. Data may bewritten to each new page (memory channel) and each page may be overwritten with new data, they canbe used over and over again. The AR8200 has 1,000 memory channels in addition to 10 quickmemory channels and a priority channel.

Each memory channel may hold:

l one frequency

l

receive model tuning step

l step-adjust

l frequency offsetl attenuator settingl noise limiter statusl AFC statusl pass status

l write protect

l text comment of up to 12 characters

The alphanumeric comment may be used to ease identification at a later date and to provide text searchfacilities.

The 1,000 memory channels are divided into 20 banks, each initially having 50 channels. The memorybanks are identified by letters A, B, C, D, E, F, G, H, I, J (upper case letters) and a, b, c, d, e, f, g, h, i, j(lower case letters) and initially numbered from 00 to 49.

Examples are A00 for the first channel location in memory bank A and A49 for the last memorychannel in memory bank A. e15 is the location of memory bank e (lower case) channel 15.

During the manufacture and testing of the receiver, various test frequencies may be entered into thereceivers memory banks so the memory locations may not be completely blank.

&Note: Where memory channels and banks are empty the indication - - - is often displayed.

The stored data may be quickly and easily recalled, changed or deleted using the memory recall, editand delete facilities.

&Note: It is suggested that one or two frequencies be held in each memory bank

to make the recalling and scrolling of memory banks fluent, if no data is stored, theAR8200 may take up to 5 or 6 seconds to respond when attempting to change memorybank while the CPU checks for data.

Auto-storeWhen shipped from the factory, memory bank J is reserved for auto-store of memory channelsfrom search mode. This is a useful facility to quickly build a list of active frequencies. Please referto section 8-7-5of this manual for further information regarding AUTO-STORE.

Dynamic memory bank resizingThe lettered memory banks are regarded as a pair making a total of 100 memory channels per bank,initially equally divided between the upper and lower case letters. It is however possible to reallocate the100 channels in blocks of 10 channels between the same letters A/a, B/b, C,c etc This means that theinitial 50/50 may be reallocated as 60/40, 70/30, 80/20, 90/10, or 10/90, 20/80, 30/70, 40/60. Thisdynamic memory reallocation can be useful to optimise the memory layout where a large or smallcollection of frequencies need to be monitored without unnecessarily wasting memory banks with just afew channels occupied.

Write protectIt is possible to write protect individual memory channels to prevent accidental deletion, whole memorybanks and a global write protect facility are also available.

Memory backupThe data contents of memory and search banks are held in an flash-ROM so that no backup battery orcapacitor is required for memory retention.

&Note: When the AR8200 is switched OFF, all VFO data will be automatically stored.

Should the NiCads (or dry batteries if in use) become completely exhausted, the last storedmemory channel or last VFO data may be lost if the AR8200 is not powered-down using the

key and insufficient power is available to save the data.

5-2 Storing VFO frequencies & data into memory

It is possible to save frequencies to the ten quick memories for simple recalling but for longer-termstorage, the 1,000 main memory channels offer a better and more flexible system.

The process to save a displayed VFO frequency to memory is as follows:

a) In VFO mode, select the required frequency, mode, attenuator etc

b) to initiate memory write

c) Use the keypad, main dial or keys to select the desired memory location(BANK and CHANNEL)

d) Add a text comment (optional) or delete an existing commente) Add memory channel write protect (optional)f) Exit the menu to save the data to the specified memory location

Lets assume that you wish to store the frequency of 123.500 MHz(with the attenuator off, noise limiter off, AFC off) into memory bankE location 25 (E25) while in VFO mode with the text comment of

AIRBAND. If a mistake is made during programming, the

key to abort entry and return to 2VFO mode.

a)Start by selecting VFO mode then key in the frequency of 123.500MHz, mode and step size are set to the default auto AUT (if not

use the key sequence )

to place the AR8200 into VFO mode.

to select the desired frequency, the mode and step size will be automatically set by

the AR8200 microprocessor.

b) the key for more than one second to enter memory input mode.

One line up from the bottom of the LCD will be the legendM-WRITE with the highlight cursor positioned to the left of thebank identification letter such as j. The microprocessor willautomatically select the youngest free memory location.

c)You may change the bank identifier at this time by pushing the

keys or by typing in a three digit memory location using thenumeric keypad.

You will notice that to the right of the keypad numbers, there aresmall orange letters which are bank identifiers, available memorylocations are A - J and a - j. Key 1 is A, key 2 is B etc, ignorethe letters K - T as these are used in search mode only. The lowercase bank identifiers may be accessed pushing the CASE SHIFT

key

Remember, if you take too long entering data (90 seconds)

the display will revert to its original condition of 2VFO mode,if you are selecting the memory location via a three digitkey sequence, you only have 2 seconds before the keypadtimes-out!

Assuming that you wish to store 123.500 MHz into E25

to select bank E then select the channel,

for 25. If any data is already stored

in location E25, the bottom line of the LCD will flash with the

stored frequency. You may accept & store the data (by pushing

or add a text comment at this point (see below).

d)To add the text comment AIRBAND, then use the

main dial to select the text and the keys to move position oftext input.

A maximum of 12 characters may be added to each memorychannel, it is recommended that a minimum of three be used forefficient use of the text search feature (a minimum of 2 characters
